Hello,
As far as I know, there is no direct requirement in IEC 60601-1 that the ME EQUIPMENT has a SECONDARY CIRCUIT. Am I right?
To be more specific let's imagine the flyback converter with D2Dn LED array as a load (see the picture). Capacity of C1 and the charge voltage are quite big, say, 10mF and 1000V. The medical effect is accomplishing by applying the light from D2Dn to a skin or something like that. The device is CLASS I and it has PROTECTIVELY EARTHED ENCLOSURE. Whole the enclosure is an ACCESSIBLE PART. There are clearances and creepages between the inside circuit and the enclosure, which provide 1MOP . There aren't MOPs between different sides of transformer TR1.
Does such ME DEVICE have the right to exist? Would there be any special requirements to the power cord?
